DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing steel frame which is wound around a steel frame or a reinforcing bar which forms a column or a beam in a steel building such as a building or a bridge.

[0002]

2. Description of the Related Art Conventionally, as a reinforcing bar frame, a steel bar of 10 mm or 13 mm in diameter (having annular irregularities on the surface) is cut to an appropriate size, and these cut reinforcing bars are used as steel columns or beams. Were assembled vertically and horizontally to form a frame surrounding the steel frame, and the intersections were bound together with wires, strips, etc., to form a muscle frame.

[0003]

However, in this case, the on-site work was difficult and the strength was low. Further, in particular, the loop-shaped horizontal streak surrounding the steel frame must be inserted into the steel frame before assembling the steel frame, which is troublesome. The present invention is intended to eliminate such a drawback, and in a factory or the like, a steel frame is previously welded by arc welding or spot welding or the like to assemble into a reinforcing frame, and in some cases, a part of the steel frame can be horizontally folded as an axial bar. is there.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has four sides surrounding a portion 1 forming a column or a beam such as a steel frame or a reinforcing bar. and the vertical stripe a _1, a ₂ ··· and horizontal stripes b _1, the intersection formed a b ₂ · · · vertically and horizontally welded by welds 2 constitute each assembly a, B, C, and D along these each assembly a, B, C, assembly assembly B, an end portion b _X lateral stripes b _1, b ₂ · · · extending transversely to the longitudinal direction of the steel 1 in C is adjacent at D a, a vertical stripe a ₁ end of C, a _n
And a reinforcing frame for assembling a reinforcing bar.

[0005]

The steel frame 1 surrounding each of the assemblies A, B, C, D
Placed on the side surface of the assembly B, hooked C lateral stripes b _1, b ₂ ... end b _X, a, ... adjacent assemblies A, the longitudinal muscle a _1, a _n end of the C Then, the frame surrounding the steel frame 1 is assembled.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Part 1 for forming a column or a beam such as a steel frame or a reinforcing bar.
Along the four sides surrounding each
Vertical and horizontal stripes a₁, A_Two... and horizontal stripe b₁, B_Two・ ・
・ Each assembly is assembled by welding the intersection of the
A, B, C, and D are configured. The assemblies A and C shown in FIG.
Vertical streak a₁, A_Two... a_nIs a vertical streak a at both ends ₁,
a_nThere is a transverse muscle b₁, B_Two... end b_YIs oblique
Bend inward and longitudinal streaks a at both ends₁, A_nWrap around and melt
Touch Vertical streaks a of assemblies B and D₁, A_Two... is three
There are no vertical streaks at both ends.

[0007] These each assembly A, B, C, assembly B, an end portion b _X lateral stripes b _1, b ₂ · · · extending transversely to the longitudinal direction of the steel 1 in the C adjacent to the D Assembly A,
Bent to engage the vertical stripe a _1, a _n end of the C.

Next, the assembling method of the present invention will be described. Put each assembly A, B, C, D on the side of the steel frame 1 surrounding each,
Ends b _X of the horizontal stripes b ₁ , b _2, ... Of the assemblies B, C,.
When hooked-adjacent assemblies A, the longitudinal muscle a _1, a _n end and C, muscular frame surrounding the steel 1 is increased set. Next, a concrete frame (not shown) is assembled outside the assembled reinforcing frame, and concrete is poured into the concrete frame, thereby forming a concrete block 3 as shown by a dotted line in FIG.

When the present invention is applied to reinforced concrete having no steel frame, a reinforcing frame may be assembled outside the portion forming a bundle of reinforcing bars or other columns or beams instead of the steel frame.

[0010]

As described above, according to the present invention, each of the assemblies A, B,
C, only applying pull the horizontal stripes b _1, b ₂ ··· end b _X of the assembly in the longitudinal muscle of the ends of adjacent assemblies are placed around the steel (or muscle bundles) and D Therefore, the work on site is extremely easy and the work such as cutting and bundling of reinforcing bars can be saved.Because each part is welded, it is stronger than the conventional bundled braid frame and can save the bundling material. is there.
